Abstract

Esophageal cancer (EC) is a leading cause of cancer-related mortality worldwide. Methyltransferase-like 3 (METTL3), a key enzyme involved in m6A methylation, has been implicated in the development and progression of various cancers, including EC. However, its potential mechanism of action in EC progression remains unclear. METTL3 expression was found to be upregulated in EC tissues and cells. Knockdown of METTL3 suppressed EC cell proliferation, invasion, migration, and angiogenesis, while promoting apoptosis. Mechanistically, METTL3 maintained PIK3CA mRNA expression and stability in an m6A-dependent and IGF2BP2-dependent manner, respectively. METTL3 silencing inactivated the AKT pathway by regulating PIK3CA expression. Furthermore, overexpression of PIK3CA mitigated the effects of METTL3 silencing on the malignant growth of KYSE180 and TE1 cells in vivo and in vitro. METTL3/IGF2BP2 promoted the malignant progression of EC by activating the PIK3CA/AKT pathway. Targeting the METTL3-PIK3CA axis may offer a novel therapeutic approach for EC treatment.

期刊介绍： Thoracic Cancer aims to facilitate international collaboration and exchange of comprehensive and cutting-edge information on basic, translational, and applied clinical research in lung cancer, esophageal cancer, mediastinal cancer, breast cancer and other thoracic malignancies. Prevention, treatment and research relevant to Asia-Pacific is a focus area, but submissions from all regions are welcomed. The editors encourage contributions relevant to prevention, general thoracic surgery, medical oncology, radiology, radiation medicine, pathology, basic cancer research, as well as epidemiological and translational studies in thoracic cancer. Thoracic Cancer is the official publication of the Chinese Society of Lung Cancer, International Chinese Society of Thoracic Surgery and is endorsed by the Korean Association for the Study of Lung Cancer and the Hong Kong Cancer Therapy Society. The Journal publishes a range of article types including: Editorials, Invited Reviews, Mini Reviews, Original Articles, Clinical Guidelines, Technological Notes, Imaging in thoracic cancer, Meeting Reports, Case Reports, Letters to the Editor, Commentaries, and Brief Reports.
